Ref. Code Function Description Setting Range [Default]
F07.16
Torque boost end-point of Asyn. motor
0.1 - 50.0 (F07.03) [2.0%]
To compensate the torque drop at low
frequency, HD5L-PLUS can boost the voltage so
as to boost the torque.
F07.16 is relative to percentage of rated
frequency of motor (F07.03).
F07.17
Slip compensation gain of Asyn. motor
0.0 - 300.0 [100.0%]
F07.18 Slip compensation filter time of Asyn. motor 0.1 - 10.0 [0.1s]
F07.19
Slip compensation limit of Asyn. motor
0.0 - 250.0 [200.0%]
The slip of motor changes with the load torque, which results in the variance of motor speed.
Slip compensation (automatically adjusting the output frequency of the controller according to the load
torque of the motor) can reduce this effect.
• In driving status (actual speed < setting speed) and in
generating status (the actual speed > setting speed), the slip
compensation gain (F07.17) can be increased gradually.
• Auto slip compensation depends on rated slip of motor, so
make sure the rated frequency (F07.03) and rated Rpm
(F07.04) are set correctly.
Range of slip compensation = F07.19 × rated slip.
Rated slip = F07.03 - F07.04 × Np / 60.
•
Np is the number of motor pole pairs.
F07.20
AVR (Automatic Voltage Regulation) function
0 - 2 [1]
0: Disabled.
1: Enabled all the time.
2: Disabled in Dec. process.
• The output voltage can be regulated to maintain constant via AVR. Thus, normally the AVR function
should be enabled, especially when the input voltage is higher than the rated voltage.
• In Dec. process, if F07.20 = 0 or 2, the running current will be a little higher; While if F07.20 = 1, the motor
will decelerate steadily and the current will be smaller.
F07.21
Oscillation-suppression mode of Asyn. motor
0,1 [0]
0: Depend on exciting component.
1: Depend on torque component.
F07.22
Oscillation-suppression coefficient of Asyn. motor
0 - 200 [100]
This function is used to damp oscillation when output current is continually unstable.
• This function helps to keep the motor running smoothly through correctly adjusting the setting of
F07.22.
